Upon first glance at these photos, we were fairly sure that this German rocket wore a custom widebody. But no! Just lowering springs, a new wheel/tire setup and a giant dragon of a turbo under the hood.
From the stock 340HP, the OK-Chiptuning crew has liberated a full 111 more ponies for a 451 count. A gigantic torque plateau hits like a sledge hammer from just 2500 rpm— making this short-wheelbase 1M into the M1 it always dreamed of…!
The N54 engine series was a fairly short run for BMW. It proved to be a bit delicate and trouble-prone when fed low-quality fuels or in some climates. OK-Chiptuning first ran this straight six through their patented ‘bedi-cleaning’ to free any gunk in the motor’s guts.
From there an Evo 2 Performance intercooler, downpipe and intake from Wagner Tuning, Eisenmann race exhaust and Sachs performance clutch will be up to the task of an extra hundred ponies — and let you control the newly ferocious beast on a track with more precision.

COMPACT HIGH-FLYER AFTER “TREATMENT” at OK-CHIPTUNING
The fact that BMW 1 series M Coupé with 340 hp (= 250 kW) is not initially extremely delicate, is widely recognized. Perhaps by somebody, who owns an exemplar (from a good 6.000 models in total) of the Boliden no longer in production. The company OK-Chiptuning in Neukirchen-Vluyn, which specializes in software optimization under the lead management of Kai-Uwe OTTLINGHAUS, from time to time, takes up supposedly “incorrigible” vehicles, to prove the opposite.
Therefore, also in this case. BMW 1 series M Coupé (E82) with N54-engine year of manufacture 11-2011 comes “for treatment” to the Lower Rhine. There, the professionals of OK-Chiptuning adapt the software to the following parts: Evo 2 Performance intercooler from Wagner Tuning, the downpipes of the same origin, Eisenmann-race-exhaust system and Sachs-performance-clutch. The Bayer has been now matured to a compact high-flyer and leaves the company premises with the following performance data determined on the in-house dynamometer Dynojet 224xLC: 440 hp (= 324 kW) and 696 Nm according to EC and 451 hp (= 332 kW) and 714 Nm in accordance with standard DIN, respectively. By the way, the maximum torque is already from 2.500 U/min up to 4.500 U/min. Moreover, do not forget Vmax delimiter.
Bedi-cleaning was carried out also by OK-Chiptuning-team in advance. This is a patented cleaning method for fuel systems and intake passages. As it comes repeatedly to coking of the inlet valve with direct injection engines, this results in power loss or, in a worst-case scenario, even engine damages. According to experience, it is advisable and useful to perform such cleaning between 60.000 and 100.000 km.
Before “treatment” at OK-Chiptuning the following special features have already been installed: a wheel-tyre-combination consisting of three-piece Schmidt rims called CC-Line in 9.5×20 with 245/30 series ZR20 tyres at the front axle or in 12.5×20 with 295/25 ZR20 at the rear axle and furthermore, Monotube coil over made by H&R. Rear spoiler, carbon mirror caps as well as radiator grill and tail lights and in the interior steering wheel, selector lever and pedals are manufactured by M Performance.
